|NASA's Kepler Mission Discovery Summary, Dec. 2011|
Scientists from NASA's Kepler mission have been busy recently. The team has announced the discovery of Kepler-22b, its first confirmed planet in the habitable zone of its solar system, 600 light years away. They have also been combing through light data captured by the telescope and have released the latest number of planetary candidates team members have identified. Staff and scientists also got together (along with a special guest!) recently to celebrate 1,000 days of science operations by the...

|NASA'S Kepler Mission Discovers Its First Rocky Planet|
NASA's Kepler spacecraft has discovered Kepler-10b, its first confirmed rocky planet and the smallest transiting exoplanet discovered to date. Kepler-10b is only 1.4 times the size of Earth and has an average density of 8.8 grams per cubic centimeter, similar to that of an iron dumbbell. The planet orbits its star in only 0.84 days and is not in the habitable zone, where liquid water could exist.For more information about the Kepler mission, please visit www.nasa.gov/keplerFor more information a...

|Kepler Discovers First Earth-Sized Planets Outside Solar System|
NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun.Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth...
